Dangerously cold wind chills will blow into Minnesota by weekend's end


The coldest air of the season (so far) is headed our way.

Temperatures are going to remain fairly mild for this time of year through Saturday, but that mercury will plummet Sunday across the state. We'll start there, then go back and look at Saturday's forecast.

The big chill

Strong northwest winds will develop Saturday night, and temperatures will bottom out below zero degrees by Sunday morning. They'll most likely remain sub-zero even during the afternoon.

Northwest winds are going to stay strong at 10 to 20 mph, creating wind chills of minus 20-25 degrees. That's frostbite-in-30-minutes-or-less territory, according to the National Weather Service. Check out their chart:

The coldest night of the season appears to be Sunday night. The forecast is calling for lows in the Twin Cities near negative 12 degrees with a wind chill of negative 20 degrees.

We'll manage to crack the positives Monday, getting barely above zero degrees that afternoon; look for a high of around 2 degrees.

Minnesota remains in the deep-freeze until late next week. Temps each night will fall below zero with highs in the single digits to near 10 degrees in the Twin Cities.

In Duluth, you're looking at a high of negative 3 degrees Sunday, and 1 above Monday. A hazardous weather outlook is in effect for northeast Minnesota through next Thursday, with a wind chill of negative 35 possible Monday morning.

St. Cloud will be similar, with a minus 4 Sunday for the high, and probably 2 degrees above zero the next day.

Rochester will peak at 4 degrees or so Sunday, and likely be right around zero Monday.

Moorhead residents should prepare for a frigid high of 7 below zero Sunday, with a warm-up to about 1 degree Monday. If you're a bit farther south in the Willmar area, add a couple of degrees to each of those highs.

Look for a slight reprieve to the bone-chilling cold on Thursday.

Saturday won't be bad, though

We've got a few hours until all of that rolls in, however.

Expect a mix of sun and clouds Friday with highs reaching into the middle 20s.

Temps remain steady, only falling to the middle teens Friday night. We'll see more mild air Saturday, highs in the upper 20s, ahead of a weak clipper system, which will drop snow around the region.

The best chance of a measurable snow is in the northern third of Minnesota. As much as 3-6 inches is possible mainly along the Canadian boarder.

In the Twin Cities around an inch or less will fall. Much of that snow is going to come after sunset Saturday.
